Allergic Drug Reactions

1.3K
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

562
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Taste Buds and Receptors01:20

Taste Buds and Receptors

4.4K
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

1.6K
Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

Prevention of Further Absorption of Poison01:14

Prevention of Further Absorption of Poison

1.1K
In cases of acute poisoning, the primary objective is to prevent further absorption of the toxic substance into the body. Immediate interventions using various decontamination techniques targeting the gastrointestinal (GI) tract can achieve this. Decontamination is crucial to prevent poison from entering the systemic circulation, which involves washing affected areas with water and mild soap and removing contaminated clothing. Once external decontamination is done, attention must be turned to...

Area of Science:

  • Immunology
  • Allergology
  • Food Science

Background:

  • Shellfish allergy, an immune response to crustaceans and mollusks, is a prevalent food allergy, particularly in the Asia-Pacific region.
  • Current diagnostic methods (skin prick tests, IgE measurement) and management (food avoidance, adrenaline) for shellfish allergy are inadequate.
  • There's a significant need for advanced diagnostic techniques and safer, more effective treatments for shellfish allergy.

Purpose of the Study:

  • To review the epidemiology and molecular characteristics of shellfish allergens.
  • To discuss advancements in diagnostic methods for shellfish allergy.
  • To explore emerging immunotherapeutic strategies for shellfish allergy prevention and treatment.

Main Methods:

  • Review of epidemiological data on shellfish allergy.
  • Analysis of molecular identification and immuno-molecular features of shellfish allergens.
  • Evaluation of current and developing diagnostic and immunotherapeutic approaches.

Main Results:

  • Over two decades, knowledge of shellfish allergen molecular features has advanced.
  • Progress has been made in developing more specific diagnostic tools.
  • Novel immunotherapies, including hypoallergens and DNA vaccines, are under development.

Conclusions:

  • The understanding of shellfish allergens is improving diagnostic specificity.
  • Innovative immunotherapies show promise for effective and safe shellfish allergy treatment.
  • A potential "cure" for shellfish allergy is becoming increasingly attainable.
